TD7624AFN
TOSHIBA BIPOLAR DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
TD7624AFN
3-WIRE AND I2C BUS SYSTEM, 1.3 GHz DIRECT TWO MODULUS-TYPE FREQUENCY
SYNTHESIZER FOR TV AND CATV
The TD7624AFN can be combined with a micro CPU to create a
highly functional frequency synthesizer. The control data
conforms to 3-wire bus and standard I2C bus formats. BUS-SW
can be used to easily switch for easy tuner system set-up.
FEATURES
= Direct two modulus-type frequency synthesizer
= Standard I2C bus format control with built-in read mode
= 3-wire bus format control
= 18-bit and 19-bit automatic discrimination circuit
(when 3-wire bus selected)
= 4-bit bandswitch drive transistor
= 5-level A / D converter (when I2C bus selected)
= Frequency Step : 31.25 kHz, 50 kHz and 62.5kHz (at 4 MHz
X’tal used)
= Phase lock detector
= Four address settings via address selector (when I2C bus selected)
= Power on reset circuit
= Flat, compact package : SSOP16 (0.65 mm pitch)
= Power on reset operation condition
Bandswitch register 1 to 4
: OFF
Tuning amplifier
: ON
Tuning voltage output (Vt)
: Low level
Charge-pump output current : ±60 µA
Phase comparator reference frequency divider ratio
: 1 / 64
Weight: 0.07 g (Typ.)
Note: These devices are easy to be damaged by high static voltage or electric fields.
In regards to this, please handle with care.
